JAMES W. BRYCE, OF BROOKLYN, NEW YORK, ASSIGNOR TO INTERNATIONAL TIME RECORDING COMPANY OF NEW YORK, OF ENDIOOTT, NEW YORK, A CORPORATION OF NEW YORK.

SYSTEM FOR OPERATING TIME-RECORDERS OR TIME-INDICATORS.

Application filed June 18, 1909.

To all whom it may concern:

Be it known that I, JAMES IV. BRYCE, a citizen of the United States, and a resident of Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in Systems for OperatingTime-Recorders or Time-Indicators, of which the following is a specification.

My invention relates to systems for operating time recorders or time indicators.

It has for its object to provide a new and improved system for operating one or more time recorders or time indicators; to simplify the circuits and connections needed in such a system; to carry on such a system with a two-wire circuit; and generally to simplify, improve and cheapen the connections and appurtenances and the operation of such a system.

It consists in the novel devices and combinations herein shown and described.

In the accompanying drawings forming part of this specification, my invention is shown as embodied in a system for operating a plurality of elapsed time recorders, but it is. not limited to use with such machines or to use with a plurality of machines.

The particular construction of the time recorders 0r indicators used in my system forms no part of the invention, but as the. invention is of value in connection with elapsed time recorders, I have shown such machines in the drawings.

My invention is useful and may be adapted for use with any suitable time indicating or recording machine and with a single machine or any number of machines.

In the accompanying drawings I have shown my invention in its preferred form, and as embodied, as previously stated, in a system containing a plurality of elapsed time recorders.

Referring now to such specific embodiment and the drawings illustrating it, Fig ure 1 is a diagram of the preferred form of circuits used in such a system. Fig. 2 is a plan detail view of the reversing switch and connecting mechanism. Fig. 3 is an end view of the same parts. Fig. 4 is a vertical section taken just inside of the case of an elapsed time recorder of the form that I prefer to use in such a system as is disclosec Specification of Letters Patent.

herein. This figure gives a side view of the two armatures of the main impulse magnet of the recorder. Fig. 5 is a detailed plan view of both of the armatures of the magnet. Fig. 6 is a top View of the same recorder with the top plate broken away to show how the recorder is equipped for use in the system. Figs. 7, 8 and 9 are detailed views of cut-out mechanism preferably used in such machines, Fig. 7 being a plan of such mechanism, Fig. 8 a side view and Fig. 9 an end view of the same.

In the system illustrated in Fig. 1, three elapsed time recorders are represented by the dotted lines 186, 187 and 188. As the particular construction of these machines forms no part of the present invention, eX- cept in one or two particulars, the full construction and details of the machines are not shown in the drawings and will not be described, only enough of the parts being shown to illustrate the application of my invention to such machines. Such parts of the machines will be referred to more fully later on.

The wires 9 and 10 and their connecting parts form the main operating circuit. It will be noted that this is a two-wire circuit. This forms the main advantage of my improvement, as heretofore in the operation of systems of the general character described herein, it has been found necessary to use three wires. The main operating circuit also contains reversing means for sending the current through the circuit in one direction or the other for predetermined intervals of time. The particular means shown for this purpose consist of a reversing switch, consisting of the contact levers 75 and 7G and connecting parts. 1 represents the source of electric energy for use in the main operating circuit. 2 is the wire from the plus pole and 3 from the negative pole of the source, a a hand switch and 5 and 6 the two wires of the circuit connecting with binding posts 65 and 66 of the reversing switch. The remaining parts of the main operating circuit will be described in detail later on.

In each time recorder or indicator in the system I provide magnetic means for operating the time mechanism of such machine, so constructed or arranged as to operate a certain part of the time mechanism at each flow of the current through the main operating circuit and the magnetic means of the machine, irrespective of the direction of such current flow, so that such part of the time mechanism will be always operated at every electrical impulse sent through the operating circuit, and so as to operate another part of the time mechanism of the said machine when the current flow is in one direction, but not to operate such part when the current flow is in the opposite direction. For example, in the particular elapsed time recorders shown, the part of the time mechanism which is always operated at every current flow through the circuit consists of time-of-day indicating and recording wheels, whereas the part of the time mechanism which is operated at times, when the current flow is in one direction, but not operated at other times, when the current flow is in the opposite direction, consists of elapsed time recording wheels. By these means, the latter part of the time mechanism is cut into or out of operation at predetermined points of time and for predetermined intervals of time. And this is done with a main operating circuit consisting of two wires only, as already described. The magnetic means shown in the drawing for accomplishing this result consist of a mag net 1% provided with two armatures, one armature (Fig. adapted to be attracted by its magnet 14 at each energization and connected so as to operate the time mechanism of the machine, and a second polarized armature 17 (Figs. a, 5 and 1) adapted to be attracted by magnet 1 1 when the current flow through the magnet is in one direction, but not to be attracted when the flow is in the other direction, and adapted in one of its positions to disconnect the first armature from a part of the time mechanism it normally controls. The first armature 120 in the elapsed time recorder illustrated in the drawings connected with all of the time mechanism of the recorder and normally operates all of it, both timeof-day and elapsed time. When the current flow, however, is in the direction to cause magnet 1 1 to attract polarized armature 17, the latter is so constructed and arranged as to actuate a suitable cut-out device, to be presently described, to cause the cut-out device to operatively disconnect the first armature from part of the time mechanism, as shown from the elapsed time mechanism. Tn this way the elapsed time mechanism will be operated at certain periods of time and will not be operated at other periods of time. The cut-out device referred to is controlled by polarized armature 17 through cut-out magnet 177. Each of the other instruments in the system, 187, 188, etc., is of course provided with similar magnets, armatures and connecting devices. The magnet of instrument 187 is 14:, its polarized armature 17 and the cut-out magnet 17?; the magnet of instrument 188 is 1-1, its polarized armature 1'7 and its cut-out magnet 177".

The means shown for operating the reversing switch are, preferably, magnetically controlled. These are adapted, when energized, to move the reversing switch from one of its positions to its other position, the reversing switch being held in whichever position it is moved to. I provide clock-controlled means for actuating this magnetic control of the reversing switch, so that such control shall be exercised at predetermined points of time, but preferably between the beats of time when the main circuit controller is actuated.

The means for operating the main circuit for controlling the electrical impulses sent through it consist, preferably, of a second ary circuit, provided with a circuit controller, clock-controlled and actuated at regular beats of time, for operating a circuit cont-roller in the main operating circuit. As shown, this secondary circuit is one pro vided with a battery 21 and the clock-controlled circuit controller is represented at M; the circuit controller in the main operating circuit controlled by the secondary circuit is armature 32 of magnet 30 in the secondary circuit. .Vhen magnet 30 is energized, armature 32 is attracted and the main operating circuit is then closed by armature making contact with contact point 35. Mag net 30 is energized at predetermined points of time. As shown, it is energized every minute by means of insulated disk 4-? mounted on the second arbor of a clock movement (not shown), the single tooth of wheel 17 causing contacts 189, on arm 191 to make contact with arm for an instant when arm 191 drops off the tooth of wheel 47. The moment when arm 190 drops off the tooth, the contact is broken anc. the contacts remain separated until the tooth again causes them to make contact.

The complete main operating circuit in the normal condition of the system runs as follows. From source 1 through wire 2, switch 4:, wire 6, binding post 65, on board 113, wire 64:, binding post 5%, wire 37, arn'1a ture 32 pivoted at 81, pulled upward against tension of spring 33 away from its back stop against contact pin 35, wire 36, binding i post 53, wire arm 75 of the reversing switch, pivoted at 56, contact 73, wire 72, binding post 68 and out through main wire 9, back through main wire 10. binding post 69, wire 71, cont-act 74:, the other arm 76 of L the reversing switch pivoted at 58, ire G3, binding post 66, wire 5, switch 4, wire back to source 1. At each revolution of wheel 17, this circuit is made and immediately thereafter broken through armature 32, sending electrical impulses through the main operating circuit every minute, and feeding the time mechanism in the different instruments every minute.

In the normal condition as just described, current flows from wire 6 and binding post 68, through wire 9 and back through wire 10,wire 9 being connected with the plus side of the source of electrical energy. The di rection of this flow is changed when the reversing switch and 76 is thrown to its left-hand position, as viewed in Fig. 1. For this purpose, arms 75 and 76 are connected by an insulated link 57 pivoted at 77 and 78 to the two arms, so as to make a flexible structure. In this position of the reversing switch, the electrical impulses are sent in the reverse direction through the main operating circuit, in this case wire 6 from the plus side ofthe source being connected through arm 75 of the reversing switch and contact 70, wire 71, binding post 69 with wire 10, thus causing the flow to be out through wire 10 and back through wire 9, wire 9 being now connected through contact 68, wire 72, and the right-hand end of contact pin 73 with arm 76 of the switch and thence with binding post 66, wire 5 with the minus side of the source.

In the normal condititon. when the current flows out through wire 9, magnet 14 and its polarized armature 17 are so constructed that armature 17 will not respond. Butwhen the current flows in the opposite direction, it will respond and operate the cutout device, referred to above, and either connect or disconnect the elapsed time mechanism with operating armature 120, as will be presently described. The letters N and S on the magnet 14 and armature 17 in dicate the normal relative magnetic condition of the two when the current flow is out through wire 9 and back through wire 10. Of course, when the current flow through magnet 14 is in the reverse direction, the polarity of its poles will be reversed and armature 17 will be attracted, operating the cut-out device.

Reversing switch 75 and 76 is moved from one posit-ion to another by means of magnet 60, which is energized at predetermined points of time. The means for moving the switch, actuated by magnet 60, are arranged so that the switch will be held in either position to which it is moved. The means for thus moving and holding the switch will be described in detail later on.

The means for energizing magnet 60 are clock-controlled so as to actuate it only at predetermined points of time. The specific apparatus shown for this purpose consists of two circuit controllers, in addition to contacts 189 and 190, at 45. The first of these additional circuit controllers, or the second circuit controller, considering that of 45 as the first, is represented at 46, and the other or third circuit controller, is illustrated at 44. That at 46 consists of two arms, arm 191, carrying contact point 192, and arm 198 constructed and operated substantially like 191, 189 and 190. Both are operated by the single tooth of disk 47. The two sets of contacts, however, are arranged at opposite sides of the disk, so that the operation of contacts 192 and 193 will be between successive actuations of the other contacts, or in other words, between successive impulses sent through the main operating circuit. This is done in order to prevent interference. The third circuit controller at 44 is similarly constructed of arm 194 carrying contact 195 and arm 196. These contacts of the third circuit controller are, as shown, arranged in series with those of the second circuit controller at 46. They are brought into contact by means of a clock-controlled contact wheel 88, having mounted on it in the groove 48 insulated contact pieces 40, 41, 42 and 43. lVheel 88 is mounted on a shaft 39 connected with the clock movement (not shown) actuating disk 47. Contact wheel 38 is so connected with the clock movement as to be rotated once every twenty-four hours. The contact pieces may be arranged on its surface at any desired points. As shown, contact 40 is arranged upon the disk of the wheel at a point representing 7 a. m., 41 at 12 noon, 42 at 1 p. m. and at 5 p. m., wheel 38 revolving, as shown by the arrow in Fig. 1. lVhen each contact strikes the contact arms 194 and 196, it brings the contacts 195 and 196 together, and preferably holds them together for a time equivalent to a complete revolution of disk 47 for a purpose presently to be described. Contacts 40, 41. 42 and 43 are made of insulating ma terial. It will be seen, therefore, that at 7 oclock, 12, 1 and 5, contact will be made between 195 and 196. As this contact lasts during a complete revolution o1 disk 47 and as the contacts at 44 and 46 are in series, both breaks in the circuit will be closed whenever any of the contacts of wheel 38 are in contact with the arms 194 and 195, and the tooth or disc 47 strikes the end of the arms 191 and 193. A circuit is then closed through a magnet attracting its armature 27, and closing a circuit through the reversing-switch controlling magnet 60. Thus at a predetermined interval of time, depending upon the location upon contact wheel 38 of the different contacts, the reversing lever will be thrown from its normal position shown in Fig. 1 to its other position, causing the current flow in the main operating circuit to be reversed, and armature 17 to be attracted and magnet 177 to be energized, and the cut-out device operated, as already described.

The circuits through the three circuit controllers at $5, 16 and A respectively, consist in full as follows. That through main circuit controller runs from one side of battery 21, through wire 22, arm 190, contact 189, arm 191, wire 19, magnet 30, wire 23, back to battery 21. That through the second circuit controller at 416 and the third circuit controller at 1 1 is from one side of battery 21, through wire 51, 191, 192, 193, wire 50, 196, 195, 191-, wire 52, magnet 25, wire 23 back to battery. Insulated blocks are shown at 15, 16 and set for supporting the contact arms.

The circuit through magnet 60 is as follows. From source of power 1, wire 2, switch 1, wire 6, 7, armature 27, pivoted at 21 and attracted by magnet 25 from its back stop 28 against the tension of spring 26, contact 29, wire 8, binding post 67, wire 62, magnet 60, wire 51, 68, wire 5, switch at, wire 3 back to the source. Magnet 69 is preferably connected with the main source of power of electric energy 1 in order to get the necessary strength of magnetic pull derived from a stronger source than is the case in the secondary circuit. Lever 59, pivoted at 58, is the means for throwing the reversing switch. The means by which it is actuated from magnet 60 will be presently described.

From the above it will be seen that every minute the contacts at 15 are closed, and that energizes magnet- 30, closing the break atand in the main operating circuit, and sending an impulse out through the circuit. This energizes each magnet 1%, 1%, 1 1', etc., attracting its main armature 120, etc, and this energizes the time feeding mechanism. The flow of current is normally out through 9 and back through 10. lVith the flow in this direction, magnets 14, etc, operate all of the time mechanism of their respective machines.

ll hen one of thc contact pieces of contact wheel -18 strikes arms 19-1 and 196, at the next succeeding closing of the circuit at 416, magnet 25 is energized and this energizes magnet 60, which throws the reversing switch to its opposite position, changing the flow of current through the main operatin g circuit, so that the current flows now out through 10 and back through 9. This ope "ates polarized armature 17, which energizes cut-out magnet 177 and the cut-out mechanism is operated to connect or disconnect the elapsed time mechanism from the actuating armature 120. This either starts into operation or stops the elapsed time mechanism. '1 he parts are so arranged that when contact i-O of wheel 88 makes contact with arms 19% and 196, the cut-cut device will operatively connect armature 120 with the elapsed time mechanism and cause it to start into operation. As the cut-out device is held in the position into which it is moved, the elapsed time mechanism will remain in operation until contact 11 makes contact with arms 19-1 and 196, when the cut-out device will be again operated to disconnect the elapsed time mechanism and cause it to stop. Similarly at 12 it is started into operation and at 13 is stopped. Thus the elapsed time mechanism will be operative to add elapsed time only during working hours.

The circuit through cut-out magnet 177, when polarized armature 17 is raised, runs as follows. From wire 9 through wire 11, magnet 177, wire 15, contacts 19 and 16, polarized armature 17 pivoted at 18, and raised against the tension of its spring 111 away from its back stop 118, wire 20 and wire 12 to wire 10. 13 is an ordinary condenser connected in the usual way to the wires 11 and 12. Instruments 187 and 188 have parts corresponding in all respects to those described for 186, and in Fig. 1 the parts, as shown, are given corres )onding numbers, with the addition of aprime to each figure for instrument 187 and a second to each figure for instrument 188.

As the reversing switch and the cut-out device to be hereafter described, are both. held when moved into either position, it is necessary after each actuation of cut-out n'iagnet 1'77 and the throwing of the cut-out device to its other position, to prevent the neXt electrical impulse through the main circuit from again actuating magnet 177 and throwing the cutout device back to its initial position. For this purpose, the contacts 10, +1, 12 and 13 of contact wheel 38 are made long enough that they will hold contacts 195 and 1% together, at least a complete revolution olt' disk +17, so that the tooth. of that disk will make contacts 192 and 193 close twice, the second closing again operating magnet (30 and throwing the reversing switch back to its initial or normal position shown in Fig. 1. k therwise the next impulse sent through the main operat ing circuit from the contacts at 15 would throw the cutout device back to its position at once, thus nullifying its former movement. in this way, I arrange it so that the reverse flow of the current will take place through magnets 11, let, etc., only for one impulse and then the circuit will be restored to its normal position with the current flowing out through 9 and returning through 19. Armature 32 of magnet 30 is pivoted at and raised against the tension of spring away from its back contact 34:.

1 will now describe the specific mechanism shown in Figs. 7, 8 and 9 of the cutout mechanism for cutting the elapsed time mechanism the instrument 187 out of or into operation. In this connection, I will first briefly describe the elapsed time rccorder 187. This is only illustrated generally in the drawings, especially in Figs. 1,

5 and 6, except the details connected with the magnet and its armatures, as the detailed construction of such a machine forms no part of my present invention.

Referring to Figs. 4, 5 and 6, the instrument there shown is one provided with time mechanism of two sorts, one for purposes of indicating time-of-day and the other for indicating elapsed time. Fig. 6 shows a part of such a machine, 136 representing a card slot for the insertion of a card into the machine to have the suitable time records printed upon it, 139, 138 representing the operating handle pivoted at 137 in the framework 134. The actual time recording wheels are not shown. The only part of the time mechanism that is shown are the four timing cams 149 which actuate suitable time-of-day recording wheels (not shown), time-of-day indicating wheels 168, 168, and timing cams 150, 159 for actuating suitable elapsed time recording wheels (not shown). The means by which the timing cams drive the respective recording wheels are not shown for reasons already given, nor are all of the connections between armature 120 of magnet 14, by which it feeds forward every minute the minute cam 149 and 150 of the two sets of timing cams. Part of these are indicated in Fig. 4 and consist of a dependent lug 121 from armature 120, with a pin 122 entering a slot in lever 145 pivoted at 144 to side frame 119 and having pivoted at its outer end, at 123, a link 124 pivoted at 125 to a lever 132. This lever 132 has secured to it a rod 131, see Fig. 6, which carries a frame 171, 172 provided with feeding pawls for feeding forwardly different timing cams. These are not shown, except the pawl 197 for the minute elapsed time cap, as they form no part of the present invention, and are elsewhere shown in full and claimed, more par ticularly, in my application for Letters Patent Serial No. 497,005, filed May 19, 1909. Of course, any suitable mechanism could be employed for these purposes. 127 represents a dash-pot pivoted to the framework at 154, its piston 128 being pivoted at 130 to the other arm 133 of lever 132 which is pivoted to frame 119 at 126 and 129 being a counterweight to assist the armature in the operation of the parts. The operation of armature 120 normally causes the timing cams, both the time-of-day timing cams 149 and the elapsed time timing cams 150, to be fed forward in any well known manner so as to represent by their condition the proper time represented by the clock movement controlling the system. The time-of-day timing cams are operated at every actuation of armature 120 and, as already described, this armature is actuated at every electrical impulse sent through the main operating circuit 9 and 10, irrespective of the direction of flow of the current. Ac-

cordingly, the time-of-day timing cams 149 are fed all the time. The elapsed time timing cams 150, however, are fed only during working hours, as has been already described. In order to prevent their being fed at other times by armature 120 and connecting parts, I provide a cut-out device which is illustrated in Figs. 6, 7, 8 and 9, which I will now describe. This is accomplished through cut-out magnet 177, which serves to cut in and out clutch mechanism forming part of the connection between armature 120 and the feeding pawls for the timing cams.

197 is an actuating pawl for feeding forward the minute elapsed time timing cam 150 at each impulse of the main operating circuit. This is operated from armature 120 through a feeding frame consisting of two arms 171 connected by a cross bar 172 and loosely pivoted on shaft 185. This frame is rocked up and down through rod 131 by connections not shown, at each energization of magnet 14. Pawl 197 meshes with a ratchet wheel 150 fast with the elapsed timing cam 150. Of course, each timing cam, both elapsed timing cams and time-ofday timing cams, is provided with a corresponding feeding pawl, all of them being loosely mounted on a shaft 185 extending between and supported by sides 171 of the feeding frame and each timing cam has a corresponding ratchet wheel connected to it. By any suitable means, such as that shown in my application above referred to, the minute timing cam feeds forward the next timing cam of higher denomination, and then the next in any well known manner.

198 represents a spring for the pawl to hold it in engagement with its ratchet. Elapsed time minute feeding pawl 197 has a pin projecting sidewise from it 151. The normal position of this pin is that of the right-hand dotted lines 151 of Fig. 9, pawl 197 being in full lines. In this position, the pawl engages the teeth of ratchet 150 and at every actuation of the frame 171, as already described, the pawl rises and feeds ratchet wheel 150 forward and with it the minute elapsed time timing cam 150. This is the position of the parts during working hours, and while the pawl and pin are in this position, all of the elapsed time timing cams are fed forward. They are in this position from the time that contact 40, contact wheel 38 (Fig. 1) passes contact arms 194 and 196 until contact piece 41 closes the contact between 195 and 196, as already described. Immediately at the end of the next operation of pawl 197, cam surface 199 snaps beneath pin 151 when in its uppermost position and when this pin is moved downwardly with its pawl, it rides outside and on the exterior surface of cam 199. In Fig. 9 it is shown in this position by the left-hand dotted lines 151 and pawl 197 is shown in this left-hand position by dotted lines. Cam 199 is a movable arm pivoted at 170 to ears 181-181 of piece 175 mounted on shaft 185. (hi each succeeding actuation of pawl 197 pin 151 rides upward and downward on the exterior surface of cam 199, thus keeping its pawl 197 out of engagement with ratchet wheel 150. This, by any well known means keeps the pawls of the ratchet wheels of the elapsed timing cams of higher denomination also out contact with their respective ratcl et wheels. The mechanism for this is not shown. Accordingly, none of the elapsed time timing cams are fed forward during this period. This lasts until the next contact-piece of contact wheel 38, causes contact to be made between 195 and 196, whereupon pawl 1.97 and the other pawls of higher denomination again resume their normal position and begin to feed their respective ratchets and the timing cams accordingly. lVhcn contact piece 1 brings contacts 195 and 196 together, pin 151 again snaps over cam surface 199 and the pawl 197 and the higher pawls are again thrown t of o ierative position.

The means for throwing the pin 151 into the one or the other of these two positions are shown in Figs. 7, 8 and 9 and are as follows. It .onsists of. the electro-magnet 177, which is supported by the bent metal piece 175, which encircles shaft 185, upon which the cams of the time-ofclay mechanism and le elapsed time mechanism are located. The piece 175 is bent out so as to form bearings 161 in the ears 166 for the armature 178. T his armature is kept from the magnet by the tension spring Armature 178 162 is pivoted at 179161 to the frame 180. This spring 155 fastened at its other end to lever 17%, which is provided with a cam wiper 173 and carries at its other end cam surface 199. Lever 17% is pivoted at 17 0 to the stationary piece 175, and has a cam part 199 that at times engages the pin 151, as described. Also fast to the armature 178162 is a pawl 15S pivoted at 159 and having a tension spring 167 to hold the end of the pawl in contact with ratchet 176. A stud 157 is securely fastened to the sheet supporting member 189 for the nose of the pawl 158 to engage with to prevent overthrow. The ratchet 179 is fastened to the cam wheel 153 and they are loosely mounted on stud 156, which is fastened to the supporting member 180. as shown. 1%. click pawl 165 is pivoted at to engage ratch t 176 and is kept in that position by tension spring 167, secured to it at and to pin 169 on pawl 158 to prevent backward rotation. A stop pin 160 is arranged to keep the armature in position. [is will be seen from Fig. 7, there are twice as many teetn in the ratchet 176 as there are rises on the cam 153; consequently every time the ma net 177 operates, pawl 158 will feed the ratchet 176 forward one tooth, and the lever arm 1741 alternately left on a rise or opposite a depression of cam 153. ll hen magnet 177 is thus energized with pawl 197 and its pin 151 in its normal posi tion, that is, 'ith the pawl engagement with its ratchet 159, and cam wiper 173 comes opposite to a depression in cam wheel 153, the cam wiper cannot move down into the depr 'sion because the side of its cam surface rests against the end of pin 151 and holds the lever 174: in the position shown in Fig. 7. But on the next upward movement of pawl 197 and pin 151, the latter pin rises over the sloping surface of cam 199, whereupon lever 171 is pulled by spring 155 so that cam wiper 173 moves downward into a depression of the cam 153 and the upper sloping surface of cam 199 moves under pin 1.31. it the next downw rd movement of pin 151 and its pawl 197, the pin rides on the outer surface of cam 199, as already described, and coutini'ies to ride on it in its upward and downward movement, thus keeping pawl 197 and the pawls of the higher timing cams out of engagement with their respective ratcht .s, until the next contact piece on contact wheel 38 again energizes magnet 177, wluJ-reupon cam wiper 17 of lever 174: is pushed. outward by a rise of the cam 153 and cam surface 199 is swung to the side of pin 151. Thereupon spring 198 of pawl 197 throws the pawl and pin into their right-hand position shown in Fig. 9, thus throwing the pawl and the pawls of higher denomination into engagement with their re spective ratchet wheels. The timing cams are then fed until pin 1511 again throws pawl 197 out of engagement in the manner already described.

I will now proceed to describe the means by which magnet (50 throws the reversing switch, to wit, from one position to another, and the means by which it is held in each position until the next actuation of magnet 60. The devices for this purpose are in all substantial respects the same as those already described for throwing in and out the cutout mechanism. for connecting and disconnecting the elapsed timing cams with the driving means. The devices for this purpose are especially illustrated in Figs. 2 and As there shown, the reversing switch has fastened to its arm 76 a lever 93, pivoted at in the framework and provided with a cam surface 59, tne lever and cam surface corresponding in all substantial respects to lever 1'7-"1. and cam surface 173 of the cutout mchanism. 9-1: is an insulated block inter posed between levers and arm 7 G. Magnet is provided with an armature 89, 91. pivoted at to frame 108. Spring 92 connects the outer end of it with lever 93 and holds armature 89 against its stop 88. To

the lower end of armature 91 is pivoted at 110 a. pawl. 85, the pawl engaging ratchet wheel 81 fast with cam disk 80, both loose on stud 111 and having stop pin 8.1L These parts correspond to pawl 158, ratchet 176 and cam 153 of the cut-out mechanism. 83 is a pawl pi oted at 82 and provided with spring 109 secured to pin 87 on pawl to prevent backward rotation. The operation of the parts is in all respects similar to the corresponding parts in the cut-out mechanism. Thus at each actuation of magnet 60, ratchet wheel 81 is fed forward one tooth and cam wheel 80 is moved -forward so that alternately a rise in the cam and a depression come opposite cam surface of lever 93. This rocks lever 98 and with it the reversing lever alternately from one position to another with each energization of magnet (30.

The arm 76 of the reversing switch has mounted on it the yielding contact fingers 9S and 99 and the arm '75 has the yielding contact fingers .(S and 97. Arm 75 is insulated from its pivot by insulating block 95.

Binding post (31 has mounted with it plate 100 holding contact 70 which is adjusted by nut 103. Similarly binding post 10? has mounted with it plate 102 which carries contact 7 1 adjusted by nut 106. Binding post 68 has mounted with it plate 101 which carries contacts 7 37 3 adjusted by nuts 104: and 105.

The polarized armature 17 is composed of bar which has at its right-h and end Fig. l, piece 116 carrying contact screw 16 and is insulated from 115 by insulating piece 117 and held by screws 146-147 Contact 19 is fastened to insulating block 1&8 which is fastened to frame.

By means of my improvement, two sets of time mechanism may be employed in any one or more of the time indicators in the system and part of the time mechanism, as for can ample, time-of-day ,mechanism, may be fed always, and another part of the time mecha nism, as for example, elapsed time mechanism, may be fed only at certain predeter mined intervals of time, such for instance as the working hours of each day, and this is accomplished by means of an operating circuit having only two iv res. By my improvement, such a system 18 made much simpler and more effective, and the cost of its installation and maintenance is materially reduced.

It will, of course, be understood that many changes from or modifications in the device shown in the drawings may be made without departing from my invention. Thus for instance, instead of using a magnet with two armatures, the one operated at all times and the other constructed so as to operate only upon a reversal of the current in the circuit, two separate magnets with separate armatures could be employed, one responsive to every impulse of current through the system and the other responsive only to certain of the inpulses, as for example, by the use of an ordinary magnet and armature and a polarized magnet or armature or other our valcnt (lGflCQ. Thus also, for example,

the separate cut-out magnet 177 might be dispensed with and the work of actuating the cut-out mechanism be performed direct from the polarized armature 17 or its equivalent.

l'l'hile I prefer that the circuit controllers represented at 4.16 and 4% in Fig. 1 should be in series with each other, this is not esential. nor is it essential that two circuit con trollers be provided for this purpose, as the work, with suitable modifications, could be 2lUGO11il liSlltl by one. Again, for example, the electric power used in the mechanism might, i'l desired, be drawn from one source instead oi from two, as shown. other ways than those above specifically indicated. the devices of the drawings could be changed or modified without depa ting from my invention.

While any suitable circuit or current may be employed for making part of the magnetic means responsive at one time and not responsive at another time, 1 preier in practice, to use a reversal of current for this purpose.
